Dad told me that he didn’t think I was going to have to go through what he went through, but now he can see that he was wrong. “This fight is a never-ending fight,” he said. “There’s no end to it. I think after the ‘60s, the whole black revolution, Martin Luther King, H. Rap Brown, Stokely Carmichael and all the rest of the people, after that happened, people went to sleep,” he said. “They thought, ‘this is over.’”

YouTube is crucial part of the misinformation ecology. Not just a demand issue: its recommender algo is a "go down the rabbit hole" machine.
You watch a Trump rally: you get suggested white supremacist videos, sometimes, auto-playing. Like a gateway drug theory of engagement.
I've seen this work across the political spectrum. YouTube algo has discovered out-flanking and "red-pilling" is.. engaging. So it does.

Excellent explanatory twitter thread explaining where this movement came from (ie chan sites):

"what's the inside story on these young fascist nazis" a lot of them ended up in shock humor/lonely dude forums that nazi recruiters joined.
this isn't a fucking puzzle box, we have all the history right here. dudes ended up on various sites crossing nerdy hobbies & resentment.
a buncha fucking nerds had their various dipshit teenage beefs, many starting with resentment of women, and got radicalized.
"how did they end up nazis?" a bunch of real nazis whispered poison in their ears while becoming their only community, their only "friends".
they also used multiple levels of irony to make bigotry and fascism more acceptable by drowning it in "oh we're just joking"

'17. Watch out for the paramilitaries: When the men with guns who have always claimed to be against the system start wearing uniforms and marching around with torches and pictures of a Leader, the end is nigh. When the pro-Leader paramilitary and the official police and military intermingle, the game is over.'

Because this was a novel iteration of online anti-Semitic culture, to the normie media it was worthy of deeply concerned coverage that likely gave a bunch of anti-Semites, trolls, and anti-Semitic trolls exactly the attention and visibility they craved. All without any of them having to prove they were actually involved, meaningfully, in anti-Semitic politics. That’s just a lot of power to give to a group of anonymous online idiots without at least knowing how many of them are 15-year-old dweebs rather than, you know, actual Nazis. [...]

In the long run, as journalistic coverage of the internet is increasingly done by people with at least a baseline understanding of web culture, that coverage will improve. For now, though, things are grim: It’s hard not to feel like journalists and politicos are effectively being led around on a leash by a group of anonymous online idiots, many of whom don’t really believe in anything.
